In regards to financial instruments available for posting margin... Is cash the only option for someone trading futures? Or are other securities available to (tbills, bonds, stock…) If this is permitted would the actual holder (the trader) be entitled to receive the dividends/coupons/interest (any payments from such securities) paid while being held as margin with the central clearinghouse? I figure for OTC they can be pretty flexible in terms of whats eligible for collateral as its up to the two counterparties but I wasnt sure if exchange traded instruments only permit cash. Would this be something that could come up on the exam?
Thanks!
Thanks!
